Abstract (en)

[origin: WO2017157399A1] A floating wind turbine comprising a hull (1), a wind turbine (2) mounted on top of the hull (1) and a counterweight (3) suspended below the hull (1) by means of counterweight suspension means (18) is described. Also a method for the installation is described. The counterweight (3) comprises one or more counterweight buoyancy tanks (17). When the internal volume of the buoyancy tanks (17) is filled with air, the total buoyancy of the counterweight (3) is close to or greater than its weight. Hereby it is capable of floating in a towing / maintenance position with moderate or no support in the vertical direction from the hull (1) or other vessels. During towing, the hull substantially has the character of a barge, substantially relying on a large waterplane area and shallow draft to maintain stability. When the buoyancy tanks (17) are partly or completely flooded with water, the counterweight (3) will sink to an installed position at a level determined by the counter- weight suspension means (18). In this position the counterweight acts as a keel, stabilizing the foundation. The counterweight suspension means (18) are separately or jointly capable of transfer- ring both forces and moments to the hull (1), thereby enabling the counterweight (3) to stabilize the hull (1) when the counterweight (3) is in its installed position.
